这真是做GMAT以来碰到的第一次连答案都看不懂的情况……求大神用白话详解TAT

The average hourly wage of television assemblers in Vernland has long been significantly lower than that in
neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of
televisions sold annually in Borodia has not changed. However, recent statistics show a drop in the number of
television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of
televisions Borodia imports annually from Vernland has increased.
Which of the following is an assumption on which the argument depends?
(A) The number of television assemblers in Vernland has increased by at least as much as the number of
television assemblers in Borodia has decreased.
(B) Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
(C) The average number of hours it takes a Borodian television assembler to assemble a television has not
decreased significantly during the past three years.
(D) The number of televisions assembled annually in Vernland has increased significantly during the past three
years.
(E) The difference between the hourly wage of television assemblers in Vernland and the hourly wage of
television assemblers in Borodia is likely to decrease in the next few years.

答案是这么说的：
What assumption does the argument depend on? The fact that fewer individuals in Borodia are
working as TV assemblers is offered as evidence that TV imports from Vernland into Borodia have
likely increased. That piece of evidence is relevant only as an indication that the number of TVs
being produced within Borodia has decreased. But a drop in the number of TV assemblers does not
indicate a drop in the number of TVs being assembled if the number of TVs an average assembler
puts together has increased. Thus, the argument must be assuming that the average time it takes an
assembler to put together a TV has not significantly decreased.

完全不能理解V城工人工资和B城电视销量有什么关系？B城税收不变又和销量有什么关系？ 求解TAT

这道题故弄玄虚，感觉前面一些条件都是没有用的，但是非常干扰判断

是F的

以下省略annually
B地TV销量=B地自生产的TV销量+B从V地进口的TV销量
                =B地工人的装配效率x B地工人数量＋B从 V地进口的TV销量

这三年来B地TV销量不变，然而近日B地工人数量减少了，为了维持等式平衡且得出结论：B从 V地进口的TV销量已经增加，那么必须满足这个assumption：即B地工人的装配效率近三年来不变。


那么我们是如何得出题目中隐含的“等式平衡”这一条件呢？要从时态、时间点入手。
三年前——————————recent：B地工人数量减少—－    现在
［                   B地TV销量不变                                              ］        
三年前—————UPDATED:B从v地进口的tv销量已经增加——现在

看到这道题, 分析了下选项,不用细纠也可以找出答案,但是关于生产效率的问题自己都想了,就贴上来.
(1) per production = (2) per work efficiency * (3) work hour,----> total production= per production* the number of workers. ---> works have been decreased, if I need totoal production do not increase, the condition is that per produciton cannot be increased.---> work hour is fixed, then per work effeciency cannot be increased. ( per means per worker)
C . The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
------- Per hour, the amount of the TV one assembler can finish is the per work effeciency. (= P/t), so here is the reciprocal of the work effciency. It means , this reciprocal cannot be decreased ; this is exact the C means.
我看了前面的所有回答,尽管思路对的,可以没有一个对工作效率作出解释,所以当中有同学会混淆涨跌的情况.
所以分享一下思路.

1. Evidence有Borodia的TV总销量不变, 而Argument认为TV从Vernland进口增加, 那么首先假设为Borodia自产TV产量减少.
2. Evidence又有Borodia的TV厂商数量减少, 那么要得到Borodia自产TV数量减少, 需假设Borodia自产TV的生产率并没有大幅提升.
3. 生产率用(生产台数/小时)来测度. 所以假设的是(生产台数/小时)并没有显著提高.
4. 这和C选项提到的"(生产每台TV所需的时长)并没有显著降低"等效.
我想到了前3点, 但第4点没想到. 最后选了一个D, 看来得继续努力.
